Hello,

is Limnia unguicornis correct here? The fly is from last week from a wet forest near Neuss (germany). Length was about 6mm.

Thanks,
Michael

Limnia is correct, and then the uniformly brown vitta on scutum suggests the rarer Limnia paludicola.

Hello Stephane,

thank you for your answer. Now that you say it I see the difference to L. unguicornis too. Is idenfication certain enough for the gallery, which still lacks L. paludicola?

Well, I have never met L. paludicola myself, but females with brown band are keyed out as L. paludicola in all litterature. If I find a species like this, it is the name I would give to it ! After, I don't know if it makes certain the identification...

It is my personal opinion, so far I'm not ready to give proof of it.
I don't think that palludicola is a valid species.

Hello Stephane, Nikita,

if we accept L. paludicola, then I guess, if all literature leads to this species, we can assume, the identification is correct. Even genetic or genital examinations are not 100% certain.

Whether to accept the species or not I let Paul decide.

Paul's, Stephane's and mine opinions are the same:
so far as nobody publish anything palludicola is a valid species.
I only wrote that at my unofficial opinion palludicola smells as species make up out of whole cloth (as well as several other Sciomyzidae, Euthycera sticticaria, for example).
As for palludicola: 1. The difference in genitalia are very doubtful my test, the matter of piont of view. 2. The colour of midstrip in female? Why not a variation? 3. The marriage of palludicola males and females. Nobody collected and examined any copulation pairs of palludicola, as far as I know. What is the reason to regard such males and females as conspecific? I can't see any...
